Ok, some more clarification from my meeting with the "main" pool contractor on Friday. But first let's get the contractor terms correct.
"Main" Pool contractor - This was the company that I signed the contract with back in Oct 2016. He advertised the ecoFinish / aquaBright finish on his website and he sold us on his ability of removing the hard bumps on the fiberglass walls of our pool and sealing the fiberglass walls and the plaster walls/floor with the ecoFinish/aquaBright finish. He did all the prep work on the walls (grinding & epoxy), removed the coping and tile band around the pool and then caulked around the coping and the concrete deck. It was only when the crew showed up to spray on the ecoFinish did I find out that he was using a sub-contractor to apply the ecoFinish. The "main" contractor was NOT trained by the ecoFinish manufacturer, nor did he have the equipment or supplies to do the work.
"Sub' contractor - This was the company from out of state that was brought in to do the actual job and was "trained" by the ecoFinish parent company on how to apply the finish and use the equipment. They have the proper ecoFinish equipment and they are the only ones that can order the ecoFinish supplies from the ecoFinish manufacturer. They are "authorized" to install the finish and apparently have exclusive territory rights for my area.
I have some questions to ask other ecoFinish aquaBright installers and pool owners that the "main" contractor is having problems understanding and the sub contractor is not responding to.
1) Seam stains on the fiberglass walls: The 1st picture below shows the problem. What type of caulking do you use (or your contractor) to seal the seam and then spray the ecoFinish over it? Did you end up having to spay the wall twice? How thick do you spray the ecoFinish on?
2) In the 2nd picture on the right you see the rust stain coming through the bottom of the wall. doesn't the ecoFinish application seal the wall and not allow water to get back to the fiberglass wall and any bolts that might be rusting? When they "fixed" the seam after the 2nd draining, they didn't attempt to cover the rust stain on the plaster ledge. Can that be sprayed over or will they have to grind the stain off and then re-apply the ecoFinish?
3) The stains (3rd picture) coming through the fiberglass walls where they had grounded down the hard lumps and epoxied are a mystery for them. Can anyone tell me what type of epoxy and/or sealer was used on their pool before the ecoFinish was sprayed on? Again it may be a thickness issue of the ecoFinish spray as well. How thick should the econFinish be sprayed on? Would another spray coat be better? Do you have to prep the first ecoFinish coat before the second coat is sprayed?
4) The 4th picture shows the soft bubble on the bottom left of the fiberglass wall. It appears that the ecoFinish did not attach itself to the fiberglass wall in those spots. They are talking about grinding those open and putting epoxy over the spot and then the "glue" that they use before they spray the ecoFinish. Is that the right procedure? The other spots in the 4th picture is where they had grounded down the hard lumps on the fiberglass walls and then put epoxy over it before they sprayed the ecoFinish. You can see that they did not do a good job on smooth out the epoxy before spraying.
5) Finally in the 5th picture is the example of the "main" pool contractors workmanship on the caulking around the copy. The contractor wants to clean of the caulking and "top coat" the caulking with another light layer of caulking to smooth it out. I am not comfortable with putting caulking over caulking and making it stick....can that be done??? or should the original caulking be cut out and new caulking put in fresh?
Again, thank you for your thoughts and comments on this project. It's coming up on eleven months since we met with the "main" contractor and signed the rehab contract but from what I have learned from many of you is that these issues are fixable but I need to help the "main" contractor and sub-contractor understand that rather than this turning ugly for all parties.
